Summary

Go to the top of the page Help

Official Symbol: ULT1
Official Full Name: Developmental regulator, ULTRAPETALA
Primary source: TAIR:AT4G28190
Locus tag: AT4G28190
See related: Araport:AT4G28190
Gene type: protein coding
RefSeq status: REVIEWED
Organism: Arabidopsis thaliana (ecotype: Columbia)
Lineage: Eukaryota; Viridiplantae; Streptophyta; Embryophyta; Tracheophyta; Spermatophyta; Magnoliopsida; eudicotyledons; Gunneridae; Pentapetalae; rosids; malvids; Brassicales; Brassicaceae; Camelineae; Arabidopsis
Also known as: F26K10.70; F26K10_70; ULT; ULTRAPETALA; ULTRAPETALA1
Summary: Encodes a novel Cys-rich protein with a B-box like domain that acts as a negative regulator of meristem cell accumulation in inflorescence and floral meristems as loss-of-function ult1 mutations cause inflorescence meristem enlargement, the production of extra flowers and floral organs, and a decrease in floral meristem determinacy. Acts opposite to CLF which represses AG, but preventing deposition of CLF repressive methylation marks.
